GAS BURNER;

To all whom it may concern:

Be it known that we, MITFonD-B. DE Loner-r and WILLIAM A. GA'ILETT, citizens of the United States, residing at Dallas, in the county of Dallas and State of Texas, have invented certain new and useful Improve ments in Gas Burners, of which the following is a specification.

This invention relates to new and useful improvements in gas burners employed for industrial purposes.

The primary object of the invention is to provide a device of this character which will be simply constructed and easy to regulate and adjust.

Another object of the invention is to provid a burner'which will emit a short but intense flame at the front of a boiler and give maximum heat in "a minimum of time, thereby conserving fuel used.

A further object of the invention is that the burners may be adjusted and regulated simultaneously with the admittance of air in front of the grate and with the flow of gas.

Nith the above and other objects in view, the invention will be more fully understood by reference to the following description, in connection with the accompanying drawings and wherein:

Figure 1 is a side elevation of the invention partly in section.

Figure 2 is a partial horizontal sectional and top view.

Figure 3 shows a detailed view of the operating or control lever.

Figure 4 is a detailed view of the door adjustment rod.

Continuing the description of the inven- .lllVGlltlOIl has the lever 15 shown in position with the gas shut off, the burner heads tion and referring to its various parts more in detail, 1 represents the housing of the apparatus, to the forward end of which are welded or otherwise suitably secured members 2 which form a grate.

Each grate 2 has a lip 2 for the burner when the latter is closed. Doors 3-3 are attached to the rear side of the housing for the purpose of admitting air into the housing andthe doors will be hereinafter referred to. Plates 33 are attached to the outside of the door and haveperforations 20-20 therein. The doors are hinged at points 21 on upright inwardly extended guide members 19. Rods 4c, slidable on members 4 and adjustable by a set screw Z), connect the doors to a packing box 10 which is slidable on a packing gland both packing box and gland 11 being slidably arranged on a gas supply pipe 12. v

A gas chamber 6 is adapted to be moved in guides 5-5, which form apart of the members l9'and has a threaded opening 6.

Pipes 7 with adjustable couplings 7 are screwed into the front face of the gas chamber 6. These pipes have laterally arranged burner heads 8 with openingsa-a and the burner heads are arranged to conformally fit the openings in the grate. These burner head openings permit a flame of gas to be projected centrally'through the apertures in the grate, and it will be seen that the burner heads are slidable. on members 1S18. A gas inlet pipe 9. is centrally s e cured in the side of the gas chamber opposite the burner pipes. The packingbox 10 forms an integral part of-this pipe and 9 represents an air-tight connection of the pipe 9 to the gas chamber. The gland 11 is adapted to slide in the packing boX and has a like attachment to the gas supply pipe 12. A valve 13 is provided for controlling the gas flow and is placed in alinement with the pipe 12, the latter being connected to a gas main 17. A square valve stem 14 has a lever 15 which is bent to form an angle of forty-five degrees from the horizontal see Figure 3. This lever has a plurality of apertures cc in its end for adjustably attaching it to the lever .16. The lever 16 it will be noted extends from and is attached to the sleeve or stufiing-box 10 and has perforations for making alteration at the point (Z.

Referring to Figure l, in operation the being seated in the grate and the doors closed. As the lever is depressed, the valve stem 14. is turned to admit the gas and at the same time the doors 3-3 are opened and the burner heads are moved away from the grate.

The supply of air through the doors and through the grate on each side of the burner and the supply of gas entering through the inlet pipe is thus controlled by a single lever.

doors is of toogreat a volume, the rods are moved in the apertures at points 2020, until the correct amount of air in relation to the influx of gas and the relation of the .If the amount of air admitted through the away from the grate, and the doors are" pulled open and the valve operated to. all ow the entrance of gas to. the chamber and to the burner heads.

When the apparatus is closed or temporarily inactive'the lever 15 is raised to the position shown in Figure 1, a point just before it reaches center.

It should be understood that changes in arrangement and construction of the invention' may be made without departing from the spirit'thereo'f andwithin the scope and meaning of the following claims:

1. An apparatus of the character described comprising a housing with doors, a grate, a plurality of burners of substantially 'T-shaped formation adapted to be moved to and away from'said grate, a gas reservoir with'a gas supply p1 pe, 'a second" pipe with a valve; and having air-tight connection with the gas supply pipe, and a lever for opening said valve and simultaneously moving saidburners away from the grate, and openingthe doors, said movement be ng reversed von'operation of the lever in an opposite direction.

2. Agasburner comprising a housing, a grate formed with the forward end thereof, said grate consisting of a-plurality of laterally extending spaced'lips having openings therein, a V-shaped'burner head for each lip having a plurality of perforations adapted to register with the openings with in said grate lips, a gas supply-pipe leading to the medial portion of each burnerhead at the side thereof opposite-to the side containing said perforations, and guides .ar-

ranged upon the opposite sides of said housing for said burners whereby the latter may be moved to and from said grate.

3. A gas burner comprising ah ousing, a grate formedwith theforward end thereof having a plural ty of horlzontally arranged openings therein, a vertically extending gas reservoir slidably mountedwithin said casing, a plurality of longitudinally extending PIPES leading from said reservoir, a burner head for each pipe adapted to be received by said horizontally extending openings 7 within said grate, a gas supply pipe; leading to oneside of said reservoir, a packing box for sa1d gas supply pipe, a main gas pipe,

a gland-secured to said main gas pipe and received by said packing box, and means operatively connected to said packing box for sliding the latter upon said gland, substantially as and-for the purpose specified.

{4. An apparatus of the character depackin'g box and doors.

voir, means connecting the burners with said reservoir, doors with adjustable means and hingedly connected to said reservoir supportlng means, a pipe connected to said reservoir and having connection with a packing box the latter connected to a gas supply pipe, a valve in said supply pipe,
